Which bullets are you shooting, at what velocity?
Spot on to 1-1/2” low would be perfect too.
Shoot at a longer range.
Ditto on previous questions about bullet weight and velocity.
For the OP, how tight is your group? Has anyone else tried your gun?
I think PPs have the right idea of trying it at greater distances.
I initially read the OP too quickly and completely missed that he was only shooting at 21'.
I highly doubt any factory sights are set for that short a range
Try it at 25 yds., it is probably factory regulated for that distance.
I can usually get about a quarter size group at 7 yards. It's what I normally shoot at.
Both 115gr and 124gr bullets will strike lower. It is highly likely that the sights were factory regulated for one of those bullet weights
What you normally shoot at has little to do with how factory sights are regulated...or even after-market sights. We old-timers are used to sights set up for 25 yards...S&W M-10s were set up for this distance shooting 158gr bullets. I have heard that some guns are now coming out of the factory set up for 15 yards.
A quarter is almost an inch in diameter. Try shooting off a bench/rest to get a feel for how far off the sights really are...being sure that you are aligning the tops of the sight blades and not aiming with the dots (they can open up your group quite a bit). There isn't much reason your gun shouldn't be able to put shots on top of each other at 7 yards...then measure how much higher they are hitting than your POA.
You might want to try some lighter bullets, to see where they are shooting.
A taller rear sight will raise the POI
The POI moves with the rear sight and inversely with the front sight
Yep my bad, I screw that up everyday and twice on Sunday. The LGS gave me a shorter rear sight to lower the POI. Thanks for the correction.
Don't change anything and try it at 25 yards. Then 50 yards. If it still hits a bit high, 'accuracy' does not matter. If the shots go high enough to miss, there's a problem.
Yes. A higher sight will lower the point of impact. From the looks of that pistol, sights should be available from the manufacturer or possibly Brownells.
But I can try out some lighter grain bullets.
I do have one more option....slightly shaving off the length of the screw. That will bring the rear sight down just a tad more. And it might make it enough difference that it would work for me.
Thanks for the replies!
I understand the frustration of POI not being where I want it, at whatever distance I choose to shoot. I understand not wanting to change ammo that functions well. I have sold guns that I couldn’t adjust because the POI upset my obsessive-compulsive disorder!
Hopefully adjusting the sight screw will work.
Even though we are probably both crazy, I wanted you to know that you’re not the only one!
I got .035" taller using 6" as the sight radius.
I did get the screw ground down a bit to where I got the rear sight as low as it will go. I'll try that out. If that doesn't do the trick,...I guess I'll have to resort to a bit taller front sight. I think the .330" should be enough I'd think. Not sure how they stay on the slide, though, without the set screw.
You can take the guesswork out by using the Front Sight Calculator on the Dawson site. The front sight is a press fit. If you need to fit it, be sure to remove material from the bottom of the sight
9mmepiphany, thanks for the heads up.
